T0 aZZ whom it may concern/.

Be it known thatI, JAMES/E. VVALLIN, a

vertical position, the wheel-rims extend below the frame-bars 1, whichare then-sup-if citizen of 'the'United States, residing at Edported bythewheels in a raised position, so

gerton, county of Rock, and State of VViscon- 1 that the device rray bereadily moved sin,haveinvented new and useful Improvements in Loaders,of which the following is a specification.

My invention'relates to improvements in loaders, with especial referenceto that class ofdevices which are used for cleaning barnyards or forgrading, excavating, &c., where it is desirable. to use a portablestructure which can be readily shifted from place to place.

The objectof this invention is to provide asupporting-incline for thescraper or fork in connection with controlling devices, whereby the forkwhen delivered to the incline n? ay be drawn up thereon, dumped, andreturned to the foot of the incline without attendance.

A further object of my invention is to provide means'whereby thestructure may be readily l'lEOVGCl from place to place and held in anyposition of adjustment with sufficient rigidity for the desired purpose.

In the following description reference is had to the accompanyingdrawings, in which Figure 1 is a perspective view of my invention. Fig.2 is a plan view of the controllingbeam. Fig. 3 is a view of the same asseen from "the upper side. Fig. 4 is a sectional view drawn on liner ofFig. 2, and Fig. 5 is a detail side view of a portion of one of thetrack-rails.

Like parts are identified by the same reference characters throughoutthe several views.

A supporting-frame comprising horizontal bars 1 and standards'2- and 3is used to support an inclined platform 4, having raised sides 5,outwardly curved at their lower ends6. Fran: e-bars 8 and 9 are used tosupport a cross-piece 10, which carries a pulley 11, through which thedraft-rope 12 passes. Braces 13 are connected to the upper portion ofthe franc, forir ed by the bars 8, 9, and 10, and the sides 5 of theplatform are provided with posts 17, over which stays'18 are passed andconnected to the'lower frame-bars 1 and to the upper-portion of theframe nearthe bar 10, whereby a rigid structure is pro duced.

Wheels 20 are mounted upon an axle-shaft 21, which is supported from across-shaft 22 by'links 23. When the-links are swungto a place to place.Pivotedbars 25, connected with the standards 3, may be swung into aposition to engage the aXle-Shaft 21 to lock the wheels'in the positionof use- When theapparatus is adjusted for use, the ba'rs 25 are swungoutwardly to their'norm al position,--as shown in Fig. 1, thuspermitting the links 236 5 to swing to an angular position, whereuponthe frame is permitted to rest upon" 'the-' ground, as shown in Fig. 3.

The scoop, comprising'a scraper or fork 30, is provided with a link 31,towh-ichthedraft- 7o rope 12 is connected. The rope passes fromthispoint of connection through an-aperture 2 in the' controlling-bar32 andupwardly above the'incline 4, overthe pulley-11, and then-r downwardlyaround a pulley 33 to the draft appliances 34. The controlling-bar-32 isprovided with pulleys 35 and-3'6 at each end, which engage theupper-andlower --m argins-'-- of track-rails 37, whereby the-bardsguided I and supported by the 'track -rails 'and-per--"-"8o mitted tomove thereon along the 1ncline.=--

When the scoop 30 is on the ground, the' controlling-bar -32 occupies aposition-near-- the lower ends of the track-rails 37*and -is locked inthat position bylatch-ba'rs 40, '8 5 which are actuated by springs41,arranged--* to'Inove the latchbars outwardly into posi--- tion toengagecatches 43 onthe'track rails 37. When the-scoop is delivered tothein-i clined' platform4, the latch-bars '40 are re 0 tractedautomatically to release the' control ling-bar and permit it to move'upwardly along the track-rails-with the scoop. Thisrelease ofthe'controlling-bar is accomplished by providing an aperture inthecontrollirig-' 9 5 bar of suflicientsize to receive the-1ink -31. Ablock 45, similarly apertured, is secured to the upper rear 'side'of thecontrolling=bar;- and another block 46 is supported ina posi tion tocover said aperture by means of flexi I00 ble supporting connectionsw47,which *are' passed over pulleys 48 on the controlling-ban and connectedwith cross-arms 49 on there spective latch-bars 40. The block 46 isprovided with a smaller aperture 50, through which the draft-rope12'passes. This aper ture, however, is too small *for'the p assageof thelink :31, so that whenthe link-strikes-the block 46 it pushes such blockforcibly away I track-rails; together with means for locking from theblock 45 and draws upon the cables 1 47, thus retracting the latch-bars40 against the tension of their actuating-springs. The latches 40 areretracted simultaneously, thus releasing the controlling-bar, which thenpasses upwardly along the incline and guides the scoop to the upper. endthereof. The link 31 is connected to the scoop by means of a pulley 55,which permits the scoo to automatically tilt under the weight the loadand dump the contents into the wagon 56. The incline 4 is preferablyprovided with a downwardly-inclined extension 57 at its upper end, whichguides the contents of the scoop to the wagon.

It will be observed that the aperture in the block 45 is eccentricallyformed with refer ence to the aperture 59 in the controlling-bar,whereby the link locks in the aperture by swinging to an angularposition under the weight of the scoop when the latter passes over theupper end of the incline 4. The object of this construction is toprevent the scoop from settling to the wagon when the draft-ropeslackens, for since the link 31 is locked to the controlling-bar thelatter, together with the scoop, will necessarily move downwardly alongthe incline by gravity as soon as permitted to do so by the draft-rope.The locked position of the link 31 is indicated by dotted lines in Fig.4.

In operation the wagon 56 is adjusted underneath the downwardly-inclinedextension 57 of the platform 4, the brace-bars 13 being arranged topermit the wa on to pass between them and the platform-supporting frame.The draft-rope is of sufficient length to permit the scoop to be carriedto any convenient point Where it is desired to fill the same, and thescoop is then drawn by the draft-rope toward the inclined platform 4until the link member 31 enters the aperture 59 in the controlling-barand releases the bar by engagin the member 46, whereupon thecontrollingar will move upwardly along the track-rails and the scoopwill move up wardly along the platform 4 until it reaches the upper endand then dumps the contents into the wagon. The draft rope is thenslackened and the scoop and controlling-bar return by gravity to thelower end of the platform 4, when the controlling-bar will beautomatically locked into position by the s pringactuated latches 40engaging the catches 43.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is
